Description
Table 1 – Comparison of larval characters of H. nigritalis, S. ambigualis and E. lacustrata.
| Segment | Character | Helenoscoparia nigritalis | Scoparia ambigualis (after Smith 2004) | Eudonia lacustrata |
|---|---|---|---|---|
| prothoracal segment | prothoracic shield | size, opacity, dark brown, trapezoid | large, shiny, semitranslucent, dark brown, rather rectangular | large, translucent, yellowish brown, trapezoid |
| with smooth outline | anterior edge with a dark, shallow rounded 'W' outline | anterior edge with straight outline | ||
| not such a border | dark sepia border around anterior and lateral edges | not such a border | ||
| setae | six macroscopic setae on anterior edge and six in postmedian region | six macroscopic setae on anterior edge and six in posterior region | six macroscopic setae on anterior edge and six in posterior region | |
| pinacula | pair of broad, elongate pinacula posterior to prothoracic shield | dark sepia prespiracular pinaculum and subventral pinaculum, each with two setae | yellowish brown prespiracular subventral pinaculum, each with two setae | |
| lateral with a broad, shield-like sclerotisation around spiraculum, subventral pinaculum very broad, each with two setae | prespiracular and subventral pinacula very close | prespiracular and subventral pinacula further apart (about one diameter of a pinaculum) | ||
| bases of legs | broad semilunar sclerotisation at bases of legs | [not described] | broad, but weak shape sclerotisation at bases of legs | |
| femur | dark brown | [not described] | yellowish brown | |
| tibia | dark brown | yellowish brown | ||
| claw | pale | [not described] | slightly more sclerotised than integument | |
| thoracic segments 2 & 3 | dorsal pinacula | two pairs of dorsal pinnacula, anterior very small, posterior very large, semicircular, anastomosed with the subdorsal pinaculum | pair of large dorsal pinacula, separated by a distance roughly equal to the diameter of a pinaculum | pair of medium dorsal pinacula, separated by a distance about 1.5 times diameter of a pinaculum |
| subdorsal pinacula | [see above] | adjacent to each dorsal pinaculum there is a large subdorsal pinaculum | adjacent to each dorsal pinaculum there is a subdorsal pinaculum of similar size | |
| lateral pinacula | two lateral pinacula, posterior larger than anterior | two large lateral pinacula | two medium sized lateral pinacula | |
| subventral pinaculum | one elongate subventral pinaculum | elongate subventral pinaculum | elongate subventral pinaculum | |
| setae | anteriodorsal pinaculum with two setae, posteriodorsal pinaculum with four setae | two setae on dorsal pinacula and anterior of lateral pinaculum | two setae on dorsal and subdorsal pinacula and anterior of lateral pinaculum | |
| one seta on subventral and posterior to lateral pinaculum | one seta on subventral and posterior to lateral pinaculum | one seta on subventral and posterior to lateral pinaculum | ||
| ventral pinacula | base of legs with circular pinaculum | ventrally a pair of unisetose pinacula | ventrally a pair of unisetose pinacula | |
| femur | concolorous with pinacula | concolorous with integument | concolorous with pinacula | |
| tibia | concolorous with pinacula | concolorous with pinacula | concolorous with pinacula | |
| tarsus | concolorous with pinacula | a little paler than integument, with grey marks on base | concolorous with pinacula | |
| setae on leg | probably up to 8 setae on each leg | about 8 setae on each leg | not examined |
